Ocean Oxygen : Suffocating the Seas

The beauty of the ocean hides within it troubling secrets, such as a decrease in oxygen levels that could lead to increasing "dead zones"

Ocean breathing – From the shallows down to its yawning depths, the ocean gets its oxygen from the surface, supplied either by the atmosphere or from the release of oxygen in phytoplankton through photosynthesis. Scientists have long known that one expected consequence from a warming climate is a gradual drop in the amount of oxygen dissolved into ocean waters as they absorb extra heat trapped in …

Shrimp Fishery Collapse in Gulf of Maine

Shrimp fishery collapse in the Gulf of Maine idles shrimp boats for 2014

Shrimp moratorium A moratorium for the 2014 shrimp fishing season was announced for the US Northeastern Gulf of Maine shrimp fishery last week as stocks of shrimp for 2012 hit record lows. The last time the shrimp catch was halted was 35 years ago in 1977. “The Northern Shrimp Technical Committee has considered the Gulf of Maine northern shrimp stock to have collapsed with …

Warming Climate Brings Sea Level Rise, Land Loss and Marine Migrations to Europe’s Seas

Sea level rise

Europe's seas are changing at an unprecedented rate, much faster than climate scientists anticipated. Seawater temperatures have been rising around 10-times faster than average over the past 25 years, while wind speeds have also been increasing. The combination of rising sea levels and stronger winds has resulted in the loss of 15% of Europe's coasts, according to recently completed EU-sponsored marine research.

Warming Oceans Lead to Massive Coral Die-off in Indonesian Waters

Water temperatures reaching as high as 93 degrees Fahrenheit in Southeast Asia’s Andamann Sea have led to a large die-off of coral reef off the coast of Indonesia, the Wildlife Conservation Society (WCS) reported earlier this week. The abnormally high ocean temperatures lasted for about a month, the report said. Surveys conducted in May, when temperatures started to peak, revealed that more than 60 …

World Fish Populations Will Shift With Changing Climate

Shifting patterns of animal migration spurred by changing climate is already clearly evident for many land-based species. Research by the Sea Around Us Project at the University of British Columbia recently published in the journal  Global Change Biology suggests the same will likely happen for ocean fisheries as well. The conclusion is that warming oceans will impact 1,066 species, from krill to shark. As …
